Stella ★★★★★

Wore this on a 10-mile trail run in full sun and the knit breathed way better than my old tee. Sun protection actually held up, no burn on my shoulders.

Stella ★★★★★

The knit is so light I honestly forgot I had it on until the sun hit my shoulders. Breathed well on a humid afternoon run and never clung when I sweated through it.

Aurora ★★★★★

Wore this on a 10-mile trail run in full sun and it never felt heavy or clingy. The knit is so light it's almost like wearing nothing, and I didn't overheat once.
